The SF/SG-S1 harmonic reducer adopts a classic three-element harmonic drive structure composed of wave generator, flexible spline and rigid spline, equipped with integrated heavy-duty crossed roller bearing inside the main body. The bearing assembly can bear radial load, axial load and overturning torque simultaneously, which eliminates the need for users to independently configure auxiliary support bearings during mechanical design, simplifies the structural design difficulty of rotary actuators and rotary platforms, and reduces the overall parts cost and assembly workload. Covering a wide reduction ratio of 30 to 160, the product can achieve obvious deceleration and high torque amplification within a compact disc-shaped structure, which is suitable for medium and heavy-load precision transmission scenarios with strict space constraints.
Different from hollow shaft harmonic reducers, this model adopts a central solid output shaft with keyway structure, which can realize direct torque transmission through key connection, with larger contact area, stronger anti-torsion ability and better reliability under heavy torque impact and positive and negative alternating load. The multi-tooth synchronous meshing transmission structure evenly distributes the tooth surface load, effectively avoiding concentrated wear and tooth breakage defects of single-tooth meshing of ordinary gear reducers, with excellent fatigue resistance and impact resistance, adapting to frequent start-stop, forward-reverse reciprocating rotation and instantaneous peak overload working conditions. All core transmission components are made of high-strength alloy steel, after precision forging, quenching and tempering heat treatment and ultra-precision grinding forming, the overall structural rigidity is outstanding, the vibration amplitude is small and the running noise is low during long-term continuous heavy-load operation.
The outer mounting flange is uniformly distributed with standard fixing bolt holes, which can be quickly locked and connected with servo motors, rotary indexing tables, clamping fixtures and mechanical swing arms, greatly shortening the coaxial alignment and assembly cycle of equipment. The internal closed cavity is filled with long-life high-temperature resistant lubricating grease to realize sealed maintenance-free operation under conventional working conditions, reduce regular lubrication maintenance work on the production line and save later operation and maintenance costs. Strict ultra-low backlash processing control ensures that the reducer can maintain stable repeated positioning accuracy after millions of cyclic rotations, and there will be no obvious motion accuracy degradation caused by gear wear and clearance increase. The optimized rotor balance design reduces the rotational inertia of the solid shaft output end, accelerates the response speed of the servo closed-loop control system, and improves the dynamic positioning performance of high-speed precision automation equipment.
SF/SG-S1 solid shaft harmonic reducer is a high-torque precision transmission core component for medium and heavy-load automation equipment requiring solid shaft torque output. It is widely used in medium-sized industrial robot joint drive, heavy-duty collaborative robot swing joints, robot wrist solid shaft output modules and mechanical fixture rotary drive units. It is also matched with heavy-duty CNC rotary indexing tables, metal processing turntables, industrial bending swing mechanisms, aerospace steering execution structures and large medical rehabilitation robot drive joints.
In addition, it is applicable to automatic welding positioners, new energy winding equipment tension drive shafts, large workpiece rotary positioning fixtures, precision testing multi-angle simulation turntables and intelligent handling equipment rotary steering mechanisms. For hydraulic servo rotary actuators and automation equipment heavy-load swing execution components, SF/SG-S1 harmonic reducer provides high-rigidity, high-overload and high-precision solid shaft transmission guarantee, meets the long-term stable operation requirements of medium and heavy-load intelligent equipment, and realizes high-precision angle positioning and flexible torque output of automated production equipment.
